مُهۡطِعِينَ مُقۡنِعِي رُءُوسِهِمۡ لَا يَرۡتَدُّ إِلَيۡهِمۡ طَرۡفُهُمۡۖ وَأَفۡـِٔدَتُهُمۡ هَوَآءٞ ٤٣
Racing ahead, their heads raised up, their glance does not come back to them,1 and their hearts are void.
Translation: Saheeh International (English)
1 This is their state at the time of resurrection from the graves. Their heads are upraised in fixed stares of terror, unable even to glance back.
Each word's meaning and sound
When people will come forth from their graves, hurrying towards the caller, with their heads raised and anxiously gazing at the sky. Their gaze does not come back to them, but remains fixed because of the horror they witness. Their hearts are empty and are unable to comprehend, and they have no sense of understanding due to the terrifying thing they witness.
